on opposite sides ofthe coating roller 28 'aremounted tension rollers,the front ten from the shaft and the latter being adjustable on the armand ofiset' 43 which carries thel shaft 44 of the V From the stand tionof such release: :'On the shaft 12 is sion roller being indicated at 34'and the rear tension roller-at35. These rollersbear down on the'paperstrip and press it against; the coating roller, the strippassing overthe top of the'coating roller-and beneath the tension rollers. At theproper time, the tension rollers are elevated to release the strip, thefollowing meansbeing provided for thispurpose:

which is journaled a rock-shaft 37 to which isconnected an arm carryinga weight '39,

held in adjusted positionbya set screw 40. Passing transversely throughthe rock-shaft, and heldadjustabl'y' in an opening therein by 'a setscrew 41,- is a stem'42 having, an

roller 35. In a like manner the'shaft 45 of the. roller 34 is carriedbya stem 46. The stems42 and 46 extend vertically downward from therock-shaft when thetension rollers are inoperative .position and theaxes of the rollers are at a right the axis of the rock-shaft.Thus,lwhen the 7 angle to weighted end of the arm 38 swings down, theshaft '37- is rocked in-a direction to swing. the tension rollersupward, clear of the paper strip. A'latch lever 47, pivoted at 48 to thestand 27, engages the ofiset 43 of thestem 42 when the-tension rollersare in operative position,- and locks the same. Upon swinging torocktoelevate the tension rollers.

Theseplates also support'the'reducing gear 50. The plate 55 is pivoted to theside'ot the standard 11 by i V a pin 57 on the latter,

the plate having a slot- 58 into which the pin extends. This connectionof the .plate55 with the standardfl-l providesla movable support for'the7 gear 50 and the shaft 52carryinglthe gear Y 53, and upon swinging thegear the plate rearward, 50 's'disconnected from the pinion 49,. thusbreaking the "driving connection between the shafts 12 and 52. Thisopera tion is efiected by an angle lever 59 fulcrumed at. 60 to a post61 rising from the base 10. The angle lever has a short arm whichisconnected to the plate 55 at 62,

Between the rear tension roller 35 andthe solution roller 28 is locatedathrow-ofi'def vice for the paper strip, it'being necessary to have ashort portion of the last end 'of the stripfree from thesolution. vThethrow-off deviceis a cross bar 74 so positioned. that when it isClOWIl-lIL inoperative position it lies beneath the strip of 7 paperbetween the i rollers 35 and 28. At the propertime, the cross bar iselevated, and'it lifts the paper strip and frees it from the roller 28.-At the ends ofthecross bar are depending arms 7 5 straddlingjthe havingguides 7 which the arms work. Beneath the tank, the arms are connectedby 1 a cross bar 77 which is connected by an an-- gular pivot bolt 78 toone endof alever 79 sides of the tank 30, the latter fulcrumed at 80 toa post 81 rising from the 7' ba se 10.; The other 'end ofthe lever 79 isconnected'to an arm 82 pivoted at one end, as indicated at 83, to asupport 84 carried:
